All About ARES

ARES Advantages

Environmental Stewardship and Sustainability
ARES produces no emissions; uses no fossil fuel; does not require water; creates no hazardous waste; requires no harmful extraction of materials; and can be cleanly decommissioned with no lasting impacts.
ARES energy storage facilities are scalable from a 10MW ancillary services installation up to a 2-3GW regional energy storage system.
Extensive Site Options
ARES sites are abundant in arid regions coincident  with wind and solar resources — maximizing transmission resources by providing  storage at the point of intermittent generation.
Constant Efficiency
An ARES system operates at a constant high efficiency over its full range of power output regardless of  discharge state.

Lower Capital Cost
ARES’ cost is approximately 60% of an equivalent power pumped - hydro facility.

Lower Operating Cost
ARES has the lowest annualized capacity cost per kW of comparable technologies.

Storage Energy, with Special Reference to Renewable Energy Sources

The expanding US western states market for energy storage is driven by the increased renewable portfolio standards, as well as the anticipated shutdown of heavy coastal generation facilities and a looming shortage of heavy inertia. There is an increasing need for large-scale, fast-responding storage facilities for ancillary services, renewables integration, load shaping, and transmission upgrade deferral.
